Source code from TeensyLC to Teensy 3.2

Hello everybody:

I have a source code for a Teensy LC, but I want translate it to a Teensy 3.2. I do not have experience with Arduino, but for a long time I develop for PIC32 and ARM STM32 microcontrollers, and also soon I will begin with NXP Kinetis. For me the more hard is C++, because all my developments with PIC32 and STM32 are in C, though I have develop something for PC with VC++.

The question is if its very hard translate source code from Teensy LC to Teensy 3.2. Currenty if I compile the source code for Teensy 3.2, there are these 3 errors:

C:\ARDUINO\hardware\teensy\avr\cores\teensy3/usb_seremu.h:90:25: error: conflicting declaration 'usb_seremu_class Serial'
extern usb_seremu_class Serial;
^
C:\ARDUINO\hardware\teensy\avr\cores\teensy3/usb_serial.h:139:25: error: 'Serial' has a previous declaration as 'usb_serial_class Serial'
extern usb_serial_class Serial;
^
C:\ARDUINO\hardware\teensy\avr\cores\teensy3/usb_keyboard.h:92:29: error: 'usb_keymedia_release_all' was not declared in this scope
usb_keymedia_release_all();
^


Thank you.

This normally can't happen. Did you mess with the USB descriptors? What USB type did you select?

Post some full compiler command lines (Settings/Preferences verbose output during compilation, if you haven't enabled that).

Thanks, I have solve already.

This is to emulate a Xbox 360 gamepad, so its not an HID USB device, but an Xinput USB device. I have add 3 lines to boards.txt file for USB Xinput Teensy 3.2, and then compile and run without errors. Now I connect Teensy 3.2 to PC by USB and Windows recognize it like an Xbox 360 gamepad. I must check IO ports because I do not know if Teensy LC and Teensy 3.2 have same pinout for IO ports, to connect buttons, joysticks, pads and rumble motors.
